Answer:
all real numbers greater can or equal to -1
Step-by-step explanation:
Given the function: f(x) = (x - 4)(x - 2)
=> its root: x =4 and x = 2
We convert the factored form into standard form: f(x) = 
As can be seen, the parameter a in the function is positive => the graph of it open up over its domain.
and then we convert the factored form into vertex form: f(x) = 
- 1
<=> when x =3 we have f(x) =1 and f(x) =-1 is the lowest point of the function
=> the range of the function: all real numbers greater can or equal to -1
Hope it will find you well.
Answer: 7,-7
Step-by-step explanation: 7 squared is 7 times 7 which equals 49
-7 times -7 is also 49 bc the negatives cancel each other out
Answer:
1. is 5
2. is -4
3. is -24
Step-by-step explanation:
i dont understand why you didnt just use a calculator but here.
First we solve this equation:
x = cos^-1(0) = pi/2 and 3pi/2
Now, this is the answer for angles between 0 and 2pi
but there are "negative angles" and angles larger than 2pi
so the general solution that includes all of these cases is:
x = pi/2 + n*pi
here n is any integer.
The product of the factors in the given expression comes to be 
.
The given expression is:
We can rewrite the given expression as
<h3>What is the exponent addition rule? </h3>
If we have two numbers with the same base we can write the product of the numbers as a single base followed by the addition of exponents.
....from exponent addition rule
So, 
Therefore, the product of the factors in the given expression comes to be .
